`DEVICE FOR,TESTING 'THE TEMPERATURE OF TOBACCO.

"Specification of Letters Patent.

n Patented sept. 3, 1912.

T o all whom it may concern Be it known that we, JOHN M. CURPHEY and JOHN W. PorNoE, citizens of the United States, residing at Dayton, in the countyof ivlontgomery and State of Ohio, have in-V vented certain new and useful Improve-A ments 1n Devices for Testing the Temperature of Tobacco, of whiclrthe following is a specification.

` Our invention relates to a device for testing the temperature of tobacco.

One of the principal objects or purposes of our invention consists, 1n producing a device, by which the temperature of tobacco when in bulk and during the process of preparing same for manufactured articles, can be readily and accurately ascertained and determined, without the 'hardship and loss of time caused by having to open the bale or packagecontaining the-tobacco, or by placing a long narrow box within said bale for the reception of the thermometer ;--tl1ese methods'being very objectionable, further objects being to provide a device as above referred to that is simple in construction; composed of few parts; can be manufactured ata minimum cost and therefore is quite inexpensive.

It will readily be understood, that while sald device is especially designed and intended for service in testing the temperature of tobacco, it can also be used in like manner for determining the temperature of any other similar articles.

Our invention consists essentially, referrlng brieliy and in general terms to the construction o`f the device, of the sectional rod vhaving the handle; the testing-tube; the' `statutes in such cases made and provided therefor.

Referring to the accompanying drawings, constituting a formal part of this specification and illustrating our inventiomas set forth in the construction of our device for A testing the temperature of tobacco ;-and

wherein the same numerals-and letters of reference indicate or point out the same parts wherever o ccurring throughout the several views z-Flgure 1, l1s a s1de view of our device for testing the temperature of tobacco. Fig. 2, is a longitudinal sectional view of 'the testingtube,'-showing the thermometer in operative position thereinbut on a slightly enlarged scale from Fig. 1,--and Fig. 3, is a transverse sectional view of the testing tube, with the thermometer removed, and taken on line aes-w3 of Fig. 1.

In describing ourv said invention speciically. and referring in detail to the various mechanical-parts, elements orV features of construction, which in combination make up our device for testing the temperature of tobacco,-by means of the characters of reerenoe as aforesaid; 7 and 8 refer to sections, which when connected-preferab1y by means of a screw-'threaded joint a,consti tute a detachable extension body, which for rigidity and firmness, is preferably in the form of a solid rod b as shown; and at the top of which is mounted a handle c for convenience when inserting the device, by forcing same into the bale or package of tobacco. Said rod, may of course be made up of as many of said sections according to the length of the lentire device desired,-which is revulated by the size and depth of the bale 1n which it is to be inserted.

Testing-tube d is detachably connected to the lower section of extension-rod b by a joint E -similar to joint a,-see Fig. 2;a and is provided with a tapered and pointed end g so as vto facilitate its insertion into the tobacco to be tested, which is formed with slotted ports or inlets z, throughwhich all hot air generated inside of the bulk of to bacco, can pass and spread up to the thermometer c, which is placed in said tube and held in position thereln by means of stops or bearings Z and m which are preferably formed of a soft material, such as cork, felt or any suitable material of a similar nature. Said testing tube having an opening nl` in its front, for reading the degrees marked on said thermometer, as the mercury therein rises or falls through the action of the heat.

Thermometer k has the degrees marked thereon as high ,as' 160 Fahrenheit, this being the highest point necessary for the mercury to rise, for the reason that tobacco will burnif the heat rises higher.

It will of course be understood that the style of .the thermometer and the number of degrees marked thereon, as well as the minor details of constructionof the device, may be slightly varied, if found ,necessary so to do,

should the device be used for testing other articles besides tobacco.

Having now fully described our device, as our inventiondwe claim 1. A device for testing the temperature of tobacco, comprising a rod made up of detachable sections; a handle mounted on one end of said rod; a testing-tube having an opened front and a tapered-and pointed end, detachably connected to the opposite end of said rod; slotted ports adapted to receive hot air formed in said tapered and pointed end of the testing-tube; and a thermometer located within said tube so that the degrees marked thereon will come in alinement with said opened front of the testing-tube.'

2. In a device for testing the temperature of tobacco, the combination of a solid detachable extension body provided at one end with a handle; va testing-tube having an opened front, and an end tapering to a point which is provided with a pluralit;r of slotted air inlets coming below said opened front, the opposite end of said tube forming a connection with the end of said extension-body; a thermometer Within said tube; and stops Within said tube for holding said thermom# eter in position. v l

In testimony whereof we aiix our signatures in presence of two witnesses.
